[ADD] last_purchased_products: sort selection by recent customer history

[danal-odoo]

Before, the product selection dropdown did not display the
time of the previous order and products were not sorted based on how
recently they were invoiced for the selected customer. Additionally,
the last invoice time and specific quantity calculations were missing
from the catalog view.

This module enhances the product selection mechanism to assist users in
identifying frequently purchased items. Specific improvements include:

• Displaying the last_order time next to the product name in the
  dropdown.
• Sorting products by last_invoice_date specific to the selected
  customer (partner).
• Showing final_qty and last_invoice_time in the product
  catalog kanban view.

If no customer is selected in the context, the standard selection
behavior and sorting apply.

  last_invoice_date Date Field, last_invoice_time field.
